3D Model: A Simple Floating Island For A Roblox Game, Shaped Roughly Square With Flat Playable Ground. The Model Should Be Under 10,000 Polygons And Vertices. The Island Has Jagged Rocky Edges And A Dark Mysterious Atmosphere. Keep The Geometry Clean And Low-poly, With Some Small Raised Areas For Variation. Add Minimal Details: A Few Twisted Low-poly Trees, Glowing Cracks In The Ground With Subtle Purple Energy, And Spiky Rocks. Use Dark Stone Textures And Simple Materials (black, Gray, Deep Purple). Avoid Unnecessary Small Details So It Runs Smoothly In Roblox.
